One of my "Red Delicious" apple trees appears to be having problems with "rust". The leaves are curling and rusty blotches have appeared on every single leaf.
I am thinking this is cedar rust based on my research and the fact that I have a "lot" of little evergreen looking weeds surrounding the tree. I think these weeds are a form of juniper. My research says to get rid of all the Juniper and to spray for the fungus. I am going to get some brush killer down on the "Juniper" today to get rid of the likely source of the problem. However, I am seeing a variety of sprays listed, but thought I would ask here if there is a sort of best of breed among sprays. Sprays I see recommended are below. Anyone have an opinion on any of these or a different spray? Triadimetone (Bayleton), ferbam (Carbamate), triforine (Funginex) and fenarimol (Rubigan) The odd thing in all this is that I have another Red Delicious that is also surrounded by the Juniper that seems to be unaffected. The 2 trees came from different places, effected tree is from Lowes ( yeah I know) and the other is from a local mom and pop nursery. Thanks |
| Do you see any shepherd hooks on the ends of the branches? Post some pictures if you can. If it's been cool and wet in your area, fire blight is a possibility. IF thats what it is, you'll need to cut the infected tree down and remove all waste to save the other trees. |
